Manhattan Project
The Manhattan Project was the code name for the Allied effort to produce the first atomic bomb during World War II. Pressure for the project began in 1939, when two scientists in Berlin accomplished atomic fission in uranium. Believing that Germany might successfully develop the first atomic bomb, Albert Einstein and other physicists persuaded President Franklin D. Roosevelt to establish a small research program in the field of Nuclear Physics. The project lasted between 1942 - 1946 and cost about $1.8 billion and it involved 125,000 people. Today, the cost of the project would be the equivalent of $20 billion. The project was more than the typical military program to achieve weapons superiority; the Manhattan Project was a scientific breakthrough, it was a breakthrough that effects our lives till this day. In June 1941 the Office of Scientific Research and Development (O.S.R.D), headed by Vannevar Bush, was created to co-ordinate all scientific efforts sponsored by the government, including the work on atomic fission. Under (O.S.R.D) the fission project expanded, involving teams at a number of universities, including Columbia, Princeton, California, and Chicago. By the spring of 1942, these teams had confirmed that atomic fissi
Some Americans thought they deserved to be taught a lesson. The effects of an atomic bomb are so awful it is necessary to ask the question "Why did the allies drop the bomb?" when the war was nearly over. -The Bomb had cost a lot of money to develop and the Americans wanted to use it. Damage is caused both by the over pressure of air at the front of the blast wave and by the extremely strong winds that persist after the wave front has passed. A flash of thermal radiation is emitted from the fireball and spreads out over a large area, but with steadily decreasing intensity. -The Japanese had been very cruel to prisoners of War. When the explosion is high in the air, the injury range for the radiation is less than for blast and fire damage or flash burns. Although the project would be extraordinarily demanding - scientifically, logistically, and financially it could be completed in time to affect the course of World War Two and the President gave his approval to proceed. Most ordinary clothing provides protection from the heat radiation. on was possible through a chain reaction in uranium. Roosevelt that the creation an atomic bomb appeared to be possible. The Americans had pushed Japan out of all the land they had occupied in the pacific region and in Europe Hitler, had been defeated. The amount of heat energy received a certain distance from the nuclear explosion depends on the power of the weapon and the state of the atmosphere. Flash burns occur only when the bare skin is directly exposed, or if the clothing is too thin to absorb the thermal radiation.
